I think some people just want to have a bunch of "stuff" in their bases more for immersion/looks kinda thing.
We have: campfire, forge, workbench, tablesaw, chemstation, cement mixer.
Cool things that would be nice:
Ammo station : reload/make ammo use less mats, fancier ammo
Stove/oven : fancier foods, cook faster. (electrical would be nice)
Fridge : power this sucker and make COLD DRINKS to take to the desert.
Medical: better healy stuff (trauma kit?)
Just like we could make things in the campfire, but use less mats if using the chemstation later on, same deal.
Of course, once you got all of those, you are going to need a larger base (or several floors).
Of course, yes, all those would look really cool in a base.
(these are more of concept things, as you progress, you can make better, more efficient stations, thus better able to
survive.)
Oh, and yeah, of course modders already do some of this, so some may/could/should be left to them to add.
(the cold drinks thing, powered fridge, workstations for some stuff, I made a buncha those for FO4. just because I wanted them,
and liked the concept. (kitchen sink chem station. I rather liked the concept, so, I made it)
NOTE: I'm on my first cup of coffee for the day, so....
